Re: Questions regarding the sandbox in iOS

FYI, iOS apps start with their working directory set to “/“ (but don’t depend on this!), so trying to write there is going to fail. NSHomeDirectory is an easy way to get your sandbox root, but you should probably be using the options the others have mentioned. Regards, Saagar Jha > On Feb 4, 2

Re: Questions regarding the sandbox in iOS

The reason for the specific sandbox questions is that my iOS app needs to call 3rd-party functions, some of which create temp files "in place" - as if they did an fopen("filename.ext","w"). Such temp files appear to be written "nowhere"... I was hoping that the sandbox might work along the lin
